You don't need to punch silly boy, god gave you elbows and he gave you feet, don't let him come to you, you go to him, when he swings for you, duck to to left, and stamp on the side of his knee cap as hard as you can and tbf, the fights pritty much over then, if it isn't take an elbow to the top of his head you you should knock him out. Size, colour, race, strength...doesn't mean f**k all if he doesn't know how to fight.
